考研英語文章一個明顯的特點就是多長難句，也是考生理解的關鍵障礙所在，而有些關鍵的障礙往往會成為出題的考點。因此，考生需要有扎實的長難句分析功底，對于句子的主要成分必須要劃分清楚，如此才能有理解正確的可能，比如：同位語、插入語、定語、不定式、分詞、各種從句等。大家平時練習中應該有意識地去分解這些句子，理解其中的句子層次和邏輯關聯。例如2000年的這篇真題：

If ambition is to be well regarded, the rewards of ambition—wealth, distinction, control over one’s destiny—must be deemed worthy of the sacrifices made on ambition’s behalf.

27.It is generally believed that ambition may be well regarded if______.

[A] its returns well compensate for the sacrifices

[B] it is rewarded with money, fame and power

[C] its goals are spiritual rather than material

[D] it is shared by the rich and the famous

理解這個句子，我們首先要抓出主干，即：the rewards of ambition must be deemed worthy of the sacrifices.雄心的回報必須要值得為此所付出的犧牲才行。A選項說他的回報必須要能補償其犧牲，正好符合原文含義。所以理清枝葉成分，抓出句子主干非常重要。再來看一個2014年的英語二真題。

In fact, those who thought that the images higher up the attractiveness scale were real directly corresponded with those who showed other markers for having higher self-esteem.

28. Epley found that people with higher self-esteem tended to______.

[A] underestimate their insecurities

[B] believe in their attractiveness

[C] cover up their depressions

[D] oversimplify their illusions

句子主干：those... corresponded with those.... 這兩類人是一致的，然后those的后邊個跟了一個定語從句，說明了具體人群。由此我們可以定位題干所問的people with higher self-esteem應該和who thought that the images higher up the attractiveness scale were real 是一致的，所以答案是B。

總之，考研英語文章多見長難句，且閱讀量偏大大，所以大家一定要關注重點考點位置，學會抓句子主干，從而快速破解長難句，正確定位答案位置，2017考研英語高效的做題!
